Abstract
The Brazed diamond grinding wheel of processing carbon fibre composite.Increasingly extensive along with composite application, secondary mechanical processing is more and more, especially when part and other parts assembly connections of carbon fibre reinforced composite, inevitably carries out large number of orifices processing.Existing cutter or drill bit add man-hour, the larger tearing defect of entrance, and outlet there will be and tears and collapse limit defect, and tool wear is accelerated, and tool life is low, and working (machining) efficiency is not high, the defect such as easily produce layering, tear.Composition of the present utility model comprises: handle of a knife (1), described handle of a knife is cylindrical knife shank, described handle of a knife connects cutter hub (2), described cutter hub is cylindrical cutter body, described cutter hub sidewall has elongated hole (3), described cutter hub right-hand member has drill bit (4), and described drill bit has one group of notch (5), described notch is evenly arranged on drill bit.The utility model is for processing carbon fibre composite.
Description
technical field:
the utility model relates to a kind of Brazed diamond grinding wheel processing carbon fibre composite.
background technology:
carbon fibre composite specific strength and specific stiffness high, have designability, formability is strong, fatigue crack-resistant performance is good and be convenient to the characteristics such as large area monolithic molding.Therefore, carbon fibre composite is applied more and more extensive in aircraft industry.Increasingly extensive along with composite application, secondary mechanical processing is more and more, especially when part and other parts assembly connections of carbon fibre reinforced composite, inevitably carries out large number of orifices processing.Existing cutter or drill bit add man-hour, the larger tearing defect of entrance, and outlet there will be and tears and collapse limit defect, and tool wear is accelerated, and tool life is low, and working (machining) efficiency is not high, the defect such as easily produce layering, tear.
utility model content:
the purpose of this utility model is to provide a kind of Brazed diamond grinding wheel processing carbon fibre composite.
above-mentioned object is realized by following technical scheme:
a kind of Brazed diamond grinding wheel processing carbon fibre composite, its composition comprises: handle of a knife, described handle of a knife is cylindrical knife shank, described handle of a knife connects cutter hub, and described cutter hub is cylindrical cutter body, and described cutter hub sidewall has elongated hole, described cutter hub right-hand member has drill bit, described drill bit has one group of notch, described notch is evenly arranged on drill bit, and described Brazed diamond grinding wheel has diamond abrasive grain cutting edge.
the beneficial effects of the utility model:
1. the Brazed diamond grinding wheel of the utility model processing carbon fibre composite can significantly improve abrasive material interface bond strength, makes diamond cutter have high-wearing feature.The diamond abrasive grain cutting edge of Brazed diamond grinding wheel is very short, and when abrasive particle cuts material simultaneously, the shear outside the plane stress of generation is less, not easily makes fibrage be produced tearing defect by starting.
the Brazed diamond grinding wheel of the utility model processing carbon fibre composite has opened an elongated hole on cutter hub sidewall, for the ease of taking out waste material; Open 4 notches at drill bit top, for convenience of chip removal, prevent chip from assembling blocking.
the utility model processing carbon fibre composite Brazed diamond grinding wheel adds fairly regular, the impulse-free robustness of entrance shape in man-hour, without tearing, quality is more excellent; Outlet shapes rule, impulse-free robustness, it is little to collapse limit scope.
the inlet mass of the Brazed diamond grinding wheel machining hole of the utility model processing carbon fibre composite is better than outgoing quality.Brazed diamond grinding wheel machining hole occurs that the critical feed speed of tearing defect is larger than hard alloy twist drill.Brazed diamond grinding wheel has higher working (machining) efficiency.Brazed diamond grinding wheel has stronger wearability than hard alloy twist drill.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is structural representations of drill bit of the present utility model.
detailed description of the invention:
embodiment 1:
a kind of Brazed diamond grinding wheel processing carbon fibre composite, its composition comprises: handle of a knife 1, described handle of a knife is cylindrical knife shank, described handle of a knife connects cutter hub 2, described cutter hub is cylindrical cutter body, and described cutter hub sidewall has elongated hole 3, and described cutter hub right-hand member has drill bit 4, described drill bit has one group of notch 5, described notch is evenly arranged on drill bit.
